AI Technical Summary
Existing door locks are prone to damage to the internal parts of the lock core due to high-speed rotation and impact force when attacked by electric drills.
An anti-drill door lock is designed. By installing an anti-drilling assembly on the mounting base, the key hole on the opposite side is matched with the counterweight block to dislocate the key hole and the lock core, preventing the electric drill from directly contacting the lock core, and entangling the electric drill through flexible strips to increase the anti-drilling effect.
It effectively prevents the damage of the door lock by the electric drill, increases the difficulty of the lock's damage resistance, and ensures the safety of the lock core.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of locks and relates to a door lock, in particular to an anti-drilling door lock. Background Art
[0002] Door locks, as important equipment to ensure the safety of homes and public places, are of various types and have different functions. When using an electric drill to drill holes in the lock core, the high-speed rotation and impact force of the drill may cause direct or indirect damage to the parts inside the lock core. Summary of the invention
[0003] The purpose of the utility model is to provide a drill-proof door lock with a simple structure in view of the above problems existing in the prior art.
[0004] The purpose of the utility model can be achieved through the following technical solutions: an anti-drill door lock, characterized in that it includes a door lock body, a lock core is provided on the door lock body, a mounting seat is provided on the door lock body, and an anti-drill component is provided on the mounting seat, the lock core protrudes from the mounting seat, a rolling bearing is provided on the anti-drill component, a guard plate is provided on the outer ring of the rolling bearing, and a keyhole is provided on the guard plate, the keyhole is arranged on one side of the center of the guard plate, a door lock shield is provided on the door lock body, and a transfer hole is provided on the shield.
[0005] In the above-mentioned anti-drilling door lock, a counterweight block is provided on one side of the guard plate.
[0006] In the above-mentioned anti-drilling door lock, a plurality of flexible strips are provided on the inner side of the key hole.
[0007] Compared with the prior art, the anti-drill door lock of the present invention prevents the door lock from being damaged by an electric drill by providing an anti-drill component, offsets the damage to the door lock caused by the rotation of the electric drill by a rolling bearing, and the keyhole biased to one side cooperates with the counterweight block to misalign the keyhole and the lock core to prevent the electric drill from directly contacting the lock core. Finally, the anti-drill effect is further enhanced by wrapping the electric drill with a flexible strip. The keyhole biased to the center side causes the electric drill to shake during attack, further increasing the difficulty of destroying the lock. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0014] like Figure 1 , 2 As shown in Figures 3 and 4, the present invention is an anti-drill door lock, comprising a door lock body 1, a lock core 3 is provided on the door lock body 1, a mounting seat 10 is provided on the door lock body 1, and an anti-drill component 2 is provided on the mounting seat 10, the lock core 3 protrudes from the mounting seat 10, a rolling bearing 9 is provided on the anti-drill component 2, a guard plate 5 is provided on the outer ring 7 of the rolling bearing 9, and a key hole 4 is opened on the guard plate 5, the key hole 4 is provided on one side of the center of the guard plate 5, and a door lock shield is provided on the door lock body 1 11, and a transfer hole 12 is opened on the shield. When installed, the anti-drilling component 2 is clamped on the mounting seat 10. Since the keyhole 4 is biased to the center side of the guard plate 5, the guard plate 5 is misaligned with the hole on the keyhole 4 and the lock core 3 under the action of gravity. When the electric drill attacks the lock core 3, the electric drill is clamped on the keyhole 4. When rotating, the guard plate 5 rotates with the electric drill to prevent the electric drill from directly attacking the lock core 3. The keyhole 4 is biased to the center side, which will cause the electric drill to shake when attacking, increasing the difficulty of destruction.
[0015] Preferably, a counterweight block 8 is provided on one side of the guard plate 5, and the counterweight block 8 is matched with the keyhole 4, so that the keyhole 4 is always non-corresponding to the lock core 3 in a natural state to prevent the drill bit from directly contacting the lock core 3. When the key is turned, the keyhole 4 is docked with the key, and the guard plate 5 is driven by turning the key until the key is stuck in the lock core 3 to complete the opening.
[0016] Preferably, a plurality of flexible strips 6 are provided on the inner side of the keyhole 4, which reduce the entry of foreign matter into the lock core 3 and increase the friction between the guard plate 5 and the drill bit, making it easier to drive the rolling bearing 9 when the electric drill rotates.
[0017] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0018] Although the present invention uses more terms such as door lock body 1, anti-drilling component 2, lock core 3, key hole 4, guard plate 5, flexible strip 6, outer ring 7, counterweight 8, rolling bearing 9, mounting seat 10, door lock shield 11, and indexing hole 12, it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
